4.0.0

BREAKING CHANGES

• Data Validations will be stored by worksheet, not cell. Index can be one or more cells or cell ranges. Issue #797 Issue #4091 Issue #4206 PR #4240
• Conditional Formatting adds Priority property and handles overlapping ranges better. Issue #4312 Issue #4318 PR #4314
• Csv Reader will no longer auto-detect Mac line endings by default. Prior behavior can be explicitly enabled via setTestAutoDetect(true), and it will not be possible at all with Php9+. Issue #4092 PR #4340
• Html Writer will now use "better boolean" logic. Booleans will now be output by default as TRUE/FALSE rather than 1/null-string. Prior behavior can be explicitly enabled via setBetterBoolean(false). PR #4340
• Xlsx Writer will now use false as the default for forceFullCalc. This affects writes with preCalculateFormulas set to false. Prior behavior can be explicitly enabled via setForceFullCalc(null).PR #4340
• Deletion of items deprecated in Release 3. See "removed" below.
